SC1202 600mA Low Dropout Positive Voltage Regulator POWER MANAGEMENT Description Features The SC1202 series of high performance positive voltage Low dropout performance, 1.3V max. regulators are designed for use in applications requiring Full current rating over line and temperature low dropout performance at full rated current. Fast transient response Additionally, the SC1202 series provides excellent 2% total output regulation over line, load regulation over variations due to line, load and and temperature temperature. Adjust pin current max. 90A over temperature Adjustable or fixed output voltages Outstanding features include low dropout performance Line regulation 0.2% max. at rated current, fast transient response, internal Load regulation 0.4% max. current limiting and thermal shutdown protection of the SOT-223 package. Fully WEEE and RoHS compliant output device. The SC1202 series are three terminal regulators available in the surface mount SOT-223 Applications package. Low voltage microcontrollers Microprocessor I/O supplies 5V to 3.3V conversion for memory, ASIC, custom circuits, etc. Typical Application Circuits Fixed Voltage Regulator U1 SC1202-3.3 3 2 TAB VIN > 4.75V VOUT = 3.3V IN OUT + + C1 C2 10uF Tant.
